China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Countersunk magnetic rings are one of the more common types of magnets, often used in outdoor applications, made of neodymium or ferrite magnets, and are designed with a center hole for easy mounting, usually with screws or bolts.
Here are some common outdoor applications for neodymium countersunk magnet rings;
Fixtures or gear for use on board a vessel
With a suitable coating, these magnets (made of neodymium) can be used for fixtures or fishing gear on board ships. They can withstand humid and salt-laden environments, and are ideal for mounting equipment or securing metal tools on deck.
Garden gate or outdoor fence
In garden gates or outdoor fences, these magnets can be screwed in place to act as a magnetic latch, ensuring that the gate closes securely while being easy to open, safe and aesthetically pleasing, and it is important to note that the magnetization of the magnets is in the direction of paired magnetization.

Outdoor signs, banners or canopy mounting systems
In outdoor sign, banner or canopy mounting systems, countersunk magnets screw into the surface, while the strong magnetic force holds metal objects firmly in place, even in windy conditions.
Emergency Rescue Equipment
On some emergency vehicles, equipment with countersunk magnets may be used to ensure quick installation and removal of necessary tools or markers on the exterior of the vehicle.
Solar Panel Mounting
This type of magnet can help secure solar panels or other devices to metal surfaces such as roofs or metal poles, providing flexibility and a strong hold, especially in installations that require repositioning.
Note: In outdoor applications, it is necessary to consider the use of anti-corrosive coatings (e.g., rubber, epoxy resin) or the selection of magnet materials suitable for outdoor environments to ensure long-term reliability.
